If a person has blood type B, that means you can only donate blood to blood types such as AB or B
If a person has O, that means it can donate blood to all blood types 
If its A, they can donate blood to blood types of AB and A
If its AB it can donate to blood types of A, B, and AB
 
        
             
        
        
        
Answer:
Explanation:
The parents phenotypes are
TTff x TtFf
The f1 genotype will be
TTFf, TTff, TtFf, Ttff
The phenotypic ratio of tall and orange colored is 4/8= ½
The phenotypic ratio for tall and white is 4/8= ½
The genotypic ratio for each is ¼
